2000 Cadillac Seville SLS from North America - Comments

The engine has had the carbon removed 9 times for a knocking sound.

The air conditioning compressor has been replace 5 times.

The ac hoses and lines were replaced because they cracked at the compressor.

The brake rotors all 4 have been replace 3 times.

The front pads were replaced with factory pads 4 times before it had 69.000. I had ceramic low noise and low dust high performance pads and have not replaced them since they are due to be replaced soon.

This car has had a bad vibration at 70 mph and up since I bought it. 4 sets of tires.

The engine was completely resealed pouring out oil.$3.500.00.

2 months later the engine was replaced after it went out of warranty. It was using 4 qts of oil to 1 tank of gas and GM would not help. It sat at the Dealer for so long waiting for parts that the brake pads had rusted to the rotors and they all had to be replaced again.

After I received the car bake there were bolts and nuts that would fall out from under the car when it was driven. The wiring harness were not reinstalled properly. The car had the same mileage when I picked it up the it had when it was taken to the Dealer ship. The ac lines had not been reinstalled in their brackets and they cracked again. The were replaced again.

After the engine was installed it was setting a bunch of codes. the PCV plastic line was cracked at the manifold. I ordered it from the same installing dealer they lost my order and it took 2 months to get the new hose assembly. It was setting codes for the secondary air pumps. I traced it down to a broken line under the intake on the drivers die rear of the engine.

I got all of the dealer screw ups repaired. I found out that the spark plugs were not changed when the engine was installed. I started to set random miss fire codes under a light load at 50 mph. I replaced the plugs and fount corrosion in the ends of 2 wires at the coil pack so I replaced all of the wires. The engine replacement was $9.856.99. almost 10 grand!!

Now after about 25 t0 30 thousand miles the engine is starting to rattle again. It will not start or run intermittently. The fuel pump sounds like a small air plain taking off.

This car has been maintained to the death. It has had in excess of $25.000.00 spent on it what a heap.

I like the way the car rides under 70 mph. When it starts it runs great. It gets great gas mileage for a 300 hp engine. 22 in town and 37 to 30 on the freeway.

I like leather interior.

I will never own another GM product. I worked for GM Dealers for 25 years.

Wow, you must really have an agenda here. Guess Cadillac is hurting sales at the BMW dealership right?

I agree with the last post. The author with the "heap of junk" must work for a competitor. Or treats his car like garbage.

I have a silver 2000 Cadillac Seville STS. 75k miles. I have replaced the brake pads, a belt, the oil every 8k, and two rotors. Most recent service was a tailight lightbulb! $2.5 + 15 minutes of my labor. Car gets 23 mpg average and pushes out 300 hp on regular gas, and has every single luxury feature possible. I fault GM for not having a car that brushes my teeth.

Mother owns a 2000 Infiniti I35. THAT car has 100k and is a piece of crap. Breaks down every 7-12k.

Anyone who seems to know all about setting codes, which implies being a mechanic, and still spends $25k on repairs is low on common sense and/or thinks I'm stupid. I own both a 97 SLS and a 2000 SLS that have given nothing but fantastic service. My previous Cads were a 1992 Deville and a 1996 Concours. Altogether close to 400,000 miles with only routine maintenance and parts replacements. My BMW 735 was much more expensive to own and not one bit more satisfying to drive.

I need HELP! I have a 2000 Seville SLS and the temp gauge is CRAZY! It keep registering hot but the engine is not really overheating. The problem is the gauge control the functionality of the engine so if the gauge tell the engine its overheating it begins to shut down! Please help me someone! Other than that... I LOVE my Caddy and Can't complain!

I purchased the car with an aftermarket warranty. My agenda is to warn people about the fact that just because it is an expensive car to purchase it is also a maintenance hog.

I am a Master ASE Tech and a GM master Tech with over 41 years of paid, hands on vehicle repair. I hold several patents on replacement parts for engine and transmissions. I build and use my own test equipment. I am working on a training program that will revolutionize the training for new and experienced Techs world wide! I am also a professional witness and I have settled several Million dollar plus legal actions on behalf of and against Auto Manufactures in state and Federal Courts. I am very tenacious. I do not give up. That is why GM brings vehicles to me to solve engineering problems, as do the National Corvette Club and the Fiero Clubs of America.

The warranty company and the dealership that I used to work for has a policy that you cannot work on your own vehicle under factory warranty or any aftermarket warranty. I have contacted the dealership that did the repair (not my dealer but a Cadillac dealer) to offer them the training that will improve there customer service and satisfaction, but I guess they would rather save their money rather than improve. I have a 99 % average customer satisfaction rating and I have maintained it for 30+ years verified through the vehicle factories and customers feed back.

The best investment that I have ever made was in purchasing the $1.400, 100 thousand mile warranty when I purchased the Seville. It not only paid for most of the repairs but provided my wife and I, 89 rental car days. over a 6 year period.

I also know that auto manufactures spend billions of dollars in repairs on new vehicles. For years US auto makers have designed cars and trucks and let the customers do the testing. If it were not for the replacement parts industry, every one would be walking in stead of riding. I also know that there are several aftermarket parts manufactures that make billions of dollars a year on replacing the poorly designed and engineered parts of cars and trucks.

The auto makers goal is to keep you tied to their dealerships for all of your repair and maintenance needs, and to eliminate the competition from the local shops. Look at the growing warranty periods that have come about in the last few years. Most customers will not go to several different shops to have other repairs done, so the dealers are providing services now that were never offered in the past, I.E. exhaust work, glass work, accessories and tires.

For the minority of you car and truck owners that have not experienced any or major problems with your vehicles that is great. But to the rest you (the majority of vehicle owners) that have had and are continuing to have, that is why there are millions of car and truck repair shops. Think about it, if vehicles were built to last there would be major financial losses around the world. There would be no repair centers needed, the pollution from parts manufactures would be gone. There would be major unemployment world wide. So to keep people employed, keep designing poorly engineer vehicles and we will all be the richer for it.

As a foot note there is a facility for GM called the DRC (Division Repair Center) or as some call it, The Last Chance Garage. If it cannot be repaired there it is crushed and sent to be recycled. If the auto makers are so good at what they do, why is it that such a facility even exists? Why is there a need for Government over site and lemon laws? Just food for thought for the some vehicle owners out there. Cheers.

Your oil consumption issue is outlined in a tech bulletin.

Your vibration is also mentioned in a tech bulletin.

In addition to that, who buys FOUR sets of tires trying to fix a problem? You'd think after the first set of fresh tires, if the problem was still there, then it must be something else.

A lot of the other faults you attribute to this car are dealer related and are not the cars fault. Sounds like the techs who worked on your car weren't very smart.

Now, regarding your vibration. Did you check the wheel bearings? It is a common problem as the stockers are not very good. Replace them with Timken sealed units and you'll be fine.

Also, do a ROAD FORCE BALANCE on the tires. The Seville chassis is very sensitive to bad tires. In conjunction with the bearing swap, your vibrations will very likely cease.

The TSB for the carbon build up and resulting oil consuption is easy to remedy. Basically go out and drive the thing like you stole it until it stops smoking. The TSB is obviously more in depth, but the idea is to run the engine as that's what it's designed for. It wasn't meant to put put around at 1400 rpm for hours on end.

I don't have an answer for your A/C issues. The A/C isn't something the car is known for failing. Crap happens I guess.

The rotors aren't particularly bad, but there are FAR better aftermarket replacements to be had that are higher quality than the OEM parts.

So, in summation, you hate the car because of a few unknown (to you AND the dealer apparently) TSBs and BAD mechanics. I can see why you'd be upset, but it's not exactly the cars fault.
